An anonymous reader writes: A group of engineers is building a new drone. What sets this apart from the hundreds of other drone development projects going on around the world? Well, these engineers are at the Kennedy Space Center, and the drone will be used to gather samples on other worlds. The drone is specifically designed to be able to fly in low- or no-atmosphere situations. Senior technologist Rob Mueller describes it as a "prospecting robot." He says, "The first step in being able to use resources on Mars or an asteroid is to find out where the resources are. They are most likely in hard-to-access areas where there is permanent shadow. Some of the crater walls are angled 30 degrees or more, and that's far too steep for a traditional rover to navigate and climb." They face major challenges with rotor and gas-jet design, they have to figure out navigation without GPS, and the whole system needs to be largely autonomous — you can't really steer a drone yourself with a latency of several minutes (or more).

schwit1 writes: If quantum computing is at the Goddard level that would be a good thing for quantum computing. This means that the major fundamental breakthrough that would put them over the top was in hand and merely a lot of investment, engineering and scaling was needed. The goal of being able to solve NP-hard or NP-Complete problems with quantum computers is similar to being able to travel to the moon, mars or deeper into space with rockets. Conventional flight could not achieve those goals because of the lack of atmosphere in space. Current computing seems like they are very limited in being able to tackle NP-hard and NP Complete problems. Although clever work in advanced mathematics and approximations can give answers that are close on a case by case basis.

MarkWhittington writes: The Houston Chronicle reported that NextGen Space LLC has released the results of a study that suggests that if the United States were to choose to do space in some new and creative ways, American moon boots could be on the lunar surface by 2021. The cost from the authorization to the first crewed lunar landing would be just $10 billion. The study was partly funded by NASA and was reviewed by the space agency and commercial space experts.

An anonymous reader writes: Elon Musk's Hyperloop project has its challenges in places that have air. But in places with little air and no fossil fuels, where you can't fly and there's little drag, it makes a lot more sense. Post-doc researcher Leon Vanstone thinks the Hyperloop may have more of a future on Mars than here on Earth. He says, "Conservative cost estimates for building a single Hyperloop track from Los Angeles to San Francisco come in at US$6 billion. Taking the technology nationwide would cost hundreds of billions of dollars more. When you consider that normal, boring airplanes already travel at about 500-600 mph – about two-thirds as fast as the Hyperloop’s predicted speed – you might begin to wonder if an extra 200 mph is enough of a payoff for those hundreds of billions of dollars. ... Well, Elon Musk is no idiot, and he certainly has the money to hire some of the best and the brightest. ... A high-speed, safe, self-powered transportation system will be vital to connect Martian settlements – likely to be few in number and separated by large distances."

StartsWithABang writes: When we talk about humans existing on worlds other than Earth, the first choice of a planet to do so on is usually Mars, a world that may have been extremely Earth-like for the first billion years of our Solar System or so. Perhaps, with enough ingenuity and resources, we could terraform it to be more like Earth is today. But the most Earth-like conditions in the Solar System don't occur on the surface of Mars, but rather in the high altitudes of Venus' atmosphere, some 50-65 km up. Despite its harsh conditions, this may be the best location for the first human colonies, for a myriad of good, scientific reasons. NASA proposed something similar last year and released a report on the subject.

MarkWhittington writes: Space visionaries dream of a time when human beings will not only settle Mars, but will terraform the Red Planet into something more Earth-like, with a breathable atmosphere, running water, and a functioning biosphere. Evidence exists that Mars was more or less Earth-like billions of years ago before the atmosphere leached away into space and the water became frozen under the ground and at the poles. Terraforming Mars is decades away from the beginning and probably centuries away from the end. But DARPA, the Defense Advanced Research Projects Agency, is already genetically engineering organisms that will help turn the Red Planet blue, according to a story in Motherboard.

pacopico writes: In a new biography on him, Elon Musk goes into gory details on his plans for colonizing Mars. The author of the book subsequently decided to run those plans by Andy Weir, the author of The Martian. Weir's book is famous for its technical acumen around getting to and from The Red Planet. His conclusion is that Musk's technology, which includes the biggest rocket ever built, is feasible — but that Musk will not be the first man on Mars. The interview also hits on the future of NASA and what we need to get to Mars. Good stuff. Weir says, "My estimate is that this will happen in 2050. NASA is saying more like 2035, but I don't have faith in Congress to fund them."

Hundreds of CubeSats have been launched to Earth orbit since 2003. Now, though, two of the small-form-factor craft are set for a deeper space mission. According to Spaceflight Now,
The twin CubeSat mission, known as Mars Cube One, will launch on an Atlas 5 rocket in March 2016 with NASA’s InSight lander. The CubeSats will relay status signals from InSight as the landing probe descends through the atmosphere, eliminating potential delays in verifying the success of the mission. ... Each Mars Cube One, or MarCO, CubeSat spacecraft measures 14.4 inches (36.6 centimeters) by 9.5 inches (24.3 centimeters) by 4.6 inches (11.8 centimeters) when closed up for launch, according to the Jet Propulsion Laboratory, which announced details of the mission Friday.
The standardized and small CubeSat has made satellite design and launching accessible to schools and others; going to Mars costs a lot more (in this case it's a "$13 million secondary mission"), but it could conceivably put interplanetary probes possible for deep-pocketed universities or corporations.

An anonymous reader writes: NASA's test of a Mars landing system came to a end Monday when the saucer-shaped vehicle's parachute tore away after partly unfurling high over the Pacific Ocean. NASA says they will provide more details at a news conference Tuesday. Another parachute failed during a similar test of a new Mars spacecraft last year. "This is exactly why we do tests like this," NASA engineer and LDSD mission commentator Dan Coatta said after the test. "When we're actually ready to send spacecraft to Mars, we know that they are going to work when that big mission is on the line."

An anonymous reader writes: When NASA has put rovers on the surface of Mars, they've relied heavily on parachutes to get through the atmosphere safely. Aerobraking doesn't work as well as it does on Earth because Mars's atmosphere is so thin. Parachuting runs into the same problem, but it's easier to pack a bigger chute than it is to bring along a bigger heat shield. But NASA has been working on that exact problem, and they'll soon test the Low-Density Supersonic Decelerator (LDSD), which looks an awful lot like a giant, inflatable donut. When a spacecraft is ready to enter an atmosphere, the LDSD will inflate along its outside edge, substantially increasing its surface area while not adding too much weight. Weather has postponed the test a couple times already, but NASA hopes to complete it on Monday.

An anonymous reader writes: Many space-related projects are currently focusing on Mars. SpaceX wants to build a colony there, NASA is looking into base design, and Mars One is supposedly picking astronauts for a mission. Because of this, we've been reading a lot about how we could live on Mars. An article at Popular Science reminds us of all the easy ways to die there. "Barring any complications with the spacecraft's hardware or any unintended run-ins with space debris, there's still a big killer lurking out in space that can't be easily avoided: radiation. ... [And] with so little atmosphere surrounding Mars, gently landing a large amount of weight on the planet will be tough. Heavy objects will pick up too much speed during the descent, making for one deep impact. ... Mars One's plan is to grow crops indoors under artificial lighting. According to the project's website, 80 square meters of space will be dedicated to plant growth within the habitat; the vegetation will be sustained using suspected water in Mars' soil, as well as carbon dioxide produced by the initial four-member crew. However, analysis conducted by MIT researchers last year (PDF) shows that those numbers just don't add up."

An anonymous reader writes: Scientists from Los Alamos National Laboratory have successfully uploaded and applied a software patch to NASA's Curiosity Rover on Mars. The patch fixes a focusing problem that cropped up in November when the laser that helps to focus one of its cameras failed. "Without this laser rangefinder, the ChemCam instrument was somewhat blind," said Roger Wiens, ChemCam principal investigator at Los Alamos. "The main laser that creates flashes of plasma when it analyzes rocks and soils up to 25 feet [7.6 meters] from the rover was not affected, but the laser analyses only work when the telescope projecting the laser light to the target is in focus." Before the fix, scientists had to shoot images at nine different focus settings to distill a decent set of data. Now, they say the new software results in better images in a single shot than even before the laser broke down. The program that runs the instrument is only 40 kilobytes in size.

An anonymous reader writes: Space policy experts are still arguing where American astronauts should go once they venture into deep space. However, there is widespread agreement that once they get there they should be prepared to stay for longer than just a few hours or days, as was the case during the Apollo missions to the moon. Taking all the material to set up habitats, the astronauts' homes away from home, would tend to be expensive. Toward the end of lowering the cost of long duration space travel, NASA has announced the 3D Printed Habitat Challenge, in partnership with America Makes, as part of the ongoing Centennial Challenge program.

SpankiMonki sends word that the United Arab Emirates has announced plans to launch a Mars mission in July, 2020. They want to send a probe (named "al-Amal",or "Hope") that will orbit the Red Planet for several years. It will analyze the Martian atmosphere, observing clouds and dust storms to help scientists figure out how water gradually escaped from Mars over a long time scale.
[A]fter being inserted into an elliptical 55-hour orbit in the first quarter of 2021, Hope will carry out its nominal two-year science mission at altitudes ranging between 22,000 to 44,000 kilometers. From there, the mission will investigate how the lower and upper levels of the Martian atmosphere are connected. One goal is to create the first global picture of how the Martian atmosphere changes throughout the day and between seasons.

braindrainbahrain writes: Elon Musk and his rocket company are well known to Slashdottters. This article and book excerpt tell the story of the creation of SpaceX and how it almost sank Musk's other company, Tesla Motors. Musk recalls, "I could either pick SpaceX or Tesla or split the money I had left between them. That was a tough decision. If I split the money, maybe both of them would die. If I gave the money to just one company, the probability of it surviving was greater, but then it would mean certain death for the other company." But then, at the last moment, years of work at SpaceX finally paid off: "[O]n Dec. 23, 2008, SpaceX received a wonderful shock. The company won a $1.6 billion contract for 12 NASA resupply flights to the space station. Then the Tesla deal ended up closing successfully, on Christmas Eve, hours before Tesla would have gone bankrupt. Musk had just a few hundred thousand dollars left and could not have made payroll the next day." Also, it turns out the inspiration for SpaceX was the idea of sending mice to Mars.
